ATTACHMENT FOR BURNING CRUDE OIL IN STOVES.

SPECIFICATION forming part of Letters Patent No. 237,623, dated February8, 1881. Application filed September 21, 1880. (No model.) I

as will enable others skilled in the art to which 1 it pertains to makeand use it, reference being had to the accompanying drawings, which formpart of this specification.

My invention relates to an improved attachment which can be applied tostoves for the purpose of burning crude oil for fuel; and it consists,first, in the use of a scroll which is inclined from its top down ward,and which terminates in a cup at the bottom, and upon which scroll theoil to be used as fuel is dropped; second, in the arrangement andcombination of parts, which will be more fully described hereinafter.

The object of my invention is to provide an attachment for stoves of allkinds so as to enable crude oil to be used in them as fuel, and whichattachmen t can be readily removed \vh enever it is desired to burnother fuel.

Figure 1 is a perspective of my attachment when used in connection witha cooking-stove. Fig. 2 is a vertical longitudinal section of the same.Fig. 3 shows a slightly-different form of the attachment which is to beused in connection with a heating-stove. Fig. 4 is a separate view ofthe scroll upon which the oil is fed. Fig. 5 is a detached view ofstop-cock G, referred to hereinafter.

A represents the central removable part of the top of a cooking-stove,and which has the two boxes B O secured to its under side in anysuitable manner, either by casting, riveting, or bolting the partstogether. These two boxes are connected together by the pipe D, so thatwhen water is poured in one box it will rise to an equal heightin theother. The boxes are separated from each other above the top of the pipeD, so as to form a chamber, b, in which the oil is forced or sprayed,and the openings between these boxes are closed by means of suitabledoors, so as to prevent a draft passing through the chamber and thuspreventing the oil from being burned in it.

The oil is fed to this attachment through the pipe E from any suitableelevated reservoir, and this space is provided with a suitable stopcockor valve,-G, for the purpose of regulating the flow of the oil,according to the degree of heat needed. The end of the stop-cock throughwhich the oil is delivered is out off short where it passes through theside of the box into the chamber where the oil is burned, and in. theplug of the stop-cock is out a small .nick, a, through which the oilpasses in avery fine stream, so that a very small fire can be kept up,and by which nick the flow of oil is kept under the most completecontrol. As the oil escapes from the end of this pipe or stopcockitisforced across the chamber and strikes against the end of the other box,and then drops down upon the top of the pipe D. Along each side of thepipe D is formed a suitable flange, G, which has a slight notch ordepression made in its center, so that the oil which runs down upon each sidefrom the top of the pipe D will be allowed to escape only at thisnotchor depression. The two boxes are kept filled with water, so as tosurround the pipe through which the oil is fed, and keep the stop-cockfrom being burned or injured by the heat; but the use of this water isnot a necessity. As

the oil escapes from this notch or depression at the center of theflange it drops off upon the grooved spiral H, which is intended to besupported just under one of the holes in the top of the stove. Thisspiral H is inclined slightly downward, and has a cup, I, formed at itsbottom, so that any oil which may not have been consumed before itreaches this cup will be caught in the cup and held until it is burned.

Where it is desired to use oil in a common heating-stove it will beunnecessary to use the two boxes, above described; but the oil-pipe willhave attached to it a sgiral which will reach out to or near the sidesof the stove. In order to make this attachment as safe as possible, theend of the oil-pipe which is next to the spiral will be inclosed in alarger pipe or shell, and this larger pipe connected, by means of asuitable vertical pipe, with an elevated reservoir of water, and thuskeep the end of the oil-pipe constantly cool and free from danger.

By using a spiral scroll, as here shown, the oil is spread over a largersurface, and thus a much greater flame is made, and a correspondingdegree of heat gained. By thus spreading the flame it will strikeagainst all parts of the bottom of the vessel above it, when used in acooking-stove, and thus heat them evenly, instead of having the heatapplied to one spot only. Where the spiral reaches out to the sides ofthe heating-stove the heat is thrown just where it is wanted, and a muchgreater amount of heat is obtained than where the fire is made in thecenter of the stove. As the stop-cockis kept immersed in water it willbe provided with a handle or wheel, so that the flow of oil can beregulated to any desired extent.

Through the end of the water-chamber in which the stop-cock is placed isalso placed another small cock, 0, so that a small quantity of watereanbe discharged in the central chamber and run down upon the scrolls.This water, mixing with the oil,is converted into steam by the heat, andthis steam, mixing with the vapor of the burning oil, causes a mostintense heat.

Having thus described my invention, I claim- 1. In combination withastove, aspiral scroll to receive the oil as itis droppedinto the stovesubstantially as shown.

2. In combination with a stove, aspiral scroll upon which the oil isdropped and which has its lower end to terminate in a cup to catch theoil which is not consumed upon the scroll itself, substantially asdescribed.

8. In combination with the removable section of a stove-cover, the twoboxes B C, a pipe provided with a stop-cock for regulating the flow ofthe oil, and a spiral scroll upon which the oil is burned, substantiallyas set forth.

4. The combination of a removable section of a stove-cover with the twoboxes B C, an intervening chamber into which the oil is fed from theoil-pipe, suitable perforated ornotehcd flanges along the edges of thechamber, and a spiral scroll upon which the oil is dropped,substantially as shown.

5. The combination of the water-chamber, a stop-cock for the oil, and astop-cock for the water, with the scroll upon which the oil is burned,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of September, 1880.
